The second option is “model”, which can be confusing at first. We associate every animation with a model, which establishes the base pose and proportions that the animation is diverging from. We also get all hierarchy information from the model. Also, any joints that are in the animation but not in the model will be stripped from the animation. We made a special model file called “Base_character” for our full-body character animations. It’s basically just a copy of our Josh model, but we called it base_character to make it easy to find.
